Abstract: A  simple  joint  is  disclosed  for  detachably connecting structural members.  The connection is made with a resilient T-shaped tongue on a first member which can be engaged in a T-shaped slot on a second member.  The tongue is engaged in the slot by rotating it about its axis. Rotation of the tongue causes the end of the tongue to be drawn into the slot by wedging action between the tongue and sloped inner surfaces of the slot.   The first and second members are held tightly together by tension which is developed in the tongue as the tongue is drawn into the slot.  The invention is well adapted for use in many fields which require parts to be detachably connected to one another such as constructing panel display systems, build-ing modular cabinets or shelving units and building modular furniture.

Granted: 1998-10-20
Abstract: ABSTRACT    The invention relates to a device and method in a paper machine for guiding a web and in particular in guiding a leader of the web.  The device operates in a paper machine in the area between a center roll of the press section and a separate press nip in the press section.  The separate press nip is formed between a smooth-faced upper roll and a hollow-faced lower roll.          Around this lower roll, a lower felt of the separate press is placed and runs from a suction-transfer roll placed at the proximity of the center roll as a straight run into the separate press nip.  At the initial end of the straight run of the felt of the separate press nip, in connection with the guide roll, air-transfer devices are arranged, by whose means a reduced pressure is produced at least across the width of the leader in connection with a closing inlet nip between the felt and the leader and/or in connection with an opening outlet nip defined between the guide roll and the straight run of the felt.

Abstract: A system management mode address correction system for a computer provides correct address values on the address bus when the computer is in system management mode.  Conventionally, bit 20 of the microprocessor's address outputs may be  masked by asserting the FORCE A20 signal.  The computer system also operates in a system management mode, which requires all of the address bits to be available for proper access to the system management interrupt vector.  When the computer is in system management mode, the computer's microprocessor asserts a system management interrupt active (SMIACT*) signal.  This signal is provided to a circuit which also receives the FORCE A20 signal. While the SMIACT signal is deactivated, the control circuit provides the true FORCE A20 signal to the computer system.  When an SMI occurs, the SMIACT signal is activated and the FORCE A20 signal is disabled.  As a result, the address generated by the microprocessor is asserted on the address bus.

Abstract: An convertible overshoe for disposition on one primary shoe and being convertible for disposition on a larger primary shoe. Each of said primary shoes has an outer surface. The overshoe is formed as an integral unit of an elastic material, e.g., rubber, and comprises a sole and an upper. The sole includes anti-slip grit on its outer surface. The upper is in the.form of a peripheral sidewall having an opening at the top edge thereof. The opening is of a sufficient size to enable a primary shoe to be extended therethrough so that it is received closely within the overshoe to prevent the overshoe from falling off. The sidewall of the upper includes a reinforcing strip in the form of a continuous thickened bead extending along a portion of the peripheral edge of the opening and spaced below that edge and an associated contiguous portion defining a trim line. The material of the sidewall at the trim line is readily severable so that it can be severed to remove the sidewall portion of the upper from it to the opening. This action forms an enlarged opening in the upper for a larger primary shoe to be extended through it into to overshoe. The reinforcing bead prevents the overshoe from tearing at the enlarged opening should that opening be stretched when the larger primary shoe is inserted therethrough.

Abstract: A method for controlling shifting of a powershift transmission of an agricultural vehicle in accordance with a boost pressure developed by a turbocharger of an engine associated with said vehicle. The turbocharger generates a turbo boost pressure which is indicative of the engine torque being produced by the engine at a given time. The turbo boost pressure is monitored by a sensor which generates a boost pressure signal in accordance with the sensed boost pressure. This signal is then modified in accordance with the sensed engine speed of the vehicle to produce a compensated turbo boost signal. The compensated turbo boost signal is compared against predetermined full-load and no-load turbo boost values to determine the percentage value of full-load boost pressure, and thus the load on the engine, at a given time. The percentage value is then used to help generate an appropriate duty cycle and time value for a pulse-width-modulated drive signal which is used to modulate the on-coming directional clutch into engagement at a desired rate of engagement dependent upon the load being experienced by the vehicle.

Title: Distributive communications network
Inventor: SMITH PHILIP JOHN
IPC: H04B10/035
Filed: 1993-09-08
Granted: 1998-06-09
Abstract: A distributive communications network comprises groups of nodes (11-22, 31-36, 41-43, 51) at different levels (1, 2, 3, 4). Each set of nodes at one level is connected to an associated node in the level above for transmission and reception of traffic. Traffic is assigned to one of a number of bands of wavelengths according to whether it is local or wider area traffic. At the first level of node (11-22) local area traffic in the corresponding band of wavelengths is looped back and retransmitted to all of the terminals (a-x) that are connected to that node. At each level of node, traffic is either passed on to a higher level, or looped back according to the band of wavelengths to which it is assigned. Thus, the wavelength band determines the node level at which the traffic is looped back, and the breadth of terminals ultimately exposed to this traffic. It is possible to re-use bands of wavelengths for communicating between terminals.
